Cheapflights.com applauds savvy penny savers and urges consumers to embrace their inner cheap.

The Oxford Dictionary describes cheap as "worth more than its cost." Sometimes, however, cheap "chic" crosses the line to tacky.

To further protect "Cheap's" good name, Cheapflights.com is outing the following celebrities for playing a hand in the cheapest moments of 2007:

1. England's royal son, Prince William, who reportedly gave girlfriend Kate Middleton fake diamond earrings as a Christmas present. A recent posting to Cheapflights.com's "Handpicked Deals" section highlighted round-trip flights to London (including two nights in a hotel) starting at $377 from New York City.

2. Socialite Paris Hilton, who according to media reports "forgot" to pay the $208 bill for the self-storage unit she rented in Los Angeles. All contents—which reportedly included diaries, photographs, contracts and love letters—were put up for sale and eventually ended up on the Internet.

3. Actress and singer Jennifer Lopez, whose net worth reportedly hovers at $100 million, for allegedly refusing to pay more than $16,000 to a limo company that rendered their services to folks including hubby Marc Anthony, her stylist and her sister during the filming of the movie "El Cantante" in New York City.

4. Lynne Spears for reportedly selling the story of her youngest daughter Jamie Lynn's pregnancy to OK! Magazine for a large sum. Deals to Louis Armstrong New Orleans International Airport, just 90 minutes from the Spears home compound in Kentwood, La., start at under $200 round trip from several major airports in the Midwest, according to a recent search on Cheapflights.com.

5. Hillary Swank, star of "Million Dollar Baby," who made the gossip rags for cashing in a $100 gift certificate at a CD store for a $99.58 bill and then asked for the 42 cents in change rather than simply tossing the card – even though a manager had to be called to open the register for the coins.

For insider information on Seattle, the largest city in the Pacific Northwest and just 90 minutes from Bellingham, Wash., where Hillary spent her formidable teen years (and probably bought her first CD), visit Cheapflights' Destination Guide.

"It's en vogue to be ‘cheap chic' these days, but some people apparently take the ‘chic' out of cheap," said Carl Schwartz, director of marketing for Cheapflights.com. "Fortunately, when it comes to travel, Americans can count on Cheapflights to help them travel on the cheap, yet still stay classy.
